PERTH, Australia — Planes are searching a new area of the Indian Ocean for possible signs of the Malaysian airliner after a new analysis of radar data suggests the plane flew faster than thought and used up more fuel, which may have reduced the distance it traveled, Australia said Friday.

Based on the new information, the Australian Maritime Safety Authority said it had shifted the search area for the jet that disappeared nearly three weeks ago to a region 1,100 kilometers (680 miles) to the northeast of where planes and ships had been trying to find any sign of it.
